COMBINED DISTRIBUTOR HEAD AND IGNITION COILS."

Application filed September 17, 1924. Serial No. 738,193.

' To alt whom t may concer/T.'

Be it known that I, IVILLIAM M. OLSON, a citizen of the United States, residing at Oak City, in the county ot Millard and State of Utah, have invented certain new and uselul Improvements in a Combined Distributor Head and Ignition Coils, of which `the following is a specification.

This invention relates to a' combined distributor head and ignitionI coil mounting adapted for use in automobile ignition systems, for replacing the usual distributor head as now used, and the separate ignition coil operating in connection therewith.

In th-e present construction of ignition system for automobiles, it is cutomary to mount the ignition coil on the dash board or other convenient part of the car, and connect the same by the proper wire connections to the contacts on the distributor and to the battery and controlling switch for the `ignition circuit, which makes it necessary to provide a high tension vwire connection between the distributor head and the ignition coil, which frequently results in a loss of current, due to the difficulty of properly insulating this high tension wire.

The present invention therefore, is designed to eliminate numerousdisadvantages of the present construction and mounting and connection of the ignition coil and the distributor head of automobile ignition systems by providing a special construction of distributor head, in which is mounted the ignition coil, having 'direct connection with the .cont-act 'for the distributor arm, and also constructed so that a circulation vot air will be permitted about the coil, for keeping the saine in a substantially cool condition, and in addition eliminating substantially all of the high tension wire connections except those between the distributor head and the spark plug.

A further object of the invention resides in providing a device of the character '.boveV mentioned, wherein a body constructed of suitable insulating material is formed with a central bore, in which is mounted the primary, secondary, and core, in proper relation, of an inductance coil, while the :aine is formed concentrically and adjacent the bore, receiving said induction coil, with a plurality of Ventilating passages in order to properly ventilate the induction coil, so that the same may be maintained in a cool state, rods membersvbeing adapted .for insertion through the outer peripheral portion ofthe body adapted to Vform circuit connections toi'v the high tension wire ofin the spark plugs and at the same time mount end caps on said bod one of which is adapted to removably ht the distributor, so

`as to mount the body thereon, in order that the contact yon the distributor arm may cooperate with contacts carried inl one of said caps for'properly interposing the 'ignition coil in the ignition circuit of theiautomobile.

The invention also includesother objects in the details of construction andarrangement of the parts whichvare more particularly pointed out in the following descrip, tion 'and claims, directed 1 to a preferredV .as described and claimed. 1

l In the drawingyforming aipartjof thi application: i Y

Figure l isa side elevation of the device,

illustrated and mounted `on the upper end The improved distributor head and coml i bined ignition coil structure includes, a body l, formed of any suitable insulatingr material, and preferably lof cylindrical form,V

which is provided in the central `portion with an axial bore 2, in which is mounted the ignition coil, including a ylaminated core 3, a primary 4, and the secondary 5,

lwhich as .i illustrated, forms Van integral body adapted to be positioned and cemented -or otherwise secured within the bore to the body. Extending longitudinally of the body and adjacent the bore 2 and arranged concentrica-lly with relation thereto, are a pluralityv ofv air passages 6, adapted to permit of the ready ventilation of the body, in order to maintain the ignition coil, in a substantially cool state, while a plurality of openings are provided adjacent the periphery of the body for receiving the rods 7, which are'headed, as indicated at 8, to provide contact points adapted to seat in recesses in the attaching cap 9, adapted to be secured over one end of the body, while the other ends of the rod 7 are adapted to receive. terminals 10, adapted to be. screw threaded or otherwise mounted thereon, for securlng the end plate 11 to the opposite end of the bod)7 ITQHL saidi capj9, in order One .terminal'of'the secondary' of the ignition coil is. connected' to a contact 14E, in the cap 9and positioned centrally thereof for contact with the carbon brush 15' carried kin the end of the distributor arm '16', which is. .rotatably mountedA on the distributor shaft 17, While, the. outer end 'of` the distribut'or" 'arm;16 i`s.`provided With a spring projccted contact 18., adaptedto engage the inside; surface of thefcap- 9 `tor contact With the head' 8 ofsaid rod 7', inY order tol complete the secondary circuit toithe vspark plugsthe`leads otvvhich are attached to the'terminals 10 on the'upper end portion of the body- .The terminalof the primary at the lower end'Lv off the coil;V is extended through` a transverse passage in the body, and connected to a* binding posty 19, mountedf on the side portion thereof, in order-that it ,may receive the Wire connecticut-'rom the usual controlling switch. provided With a binding post 20, which receives the common-terminal oi'both the primary and secondary windings of the ignition coil, and is adapted to receivethe Wire 'connections froml the batteryv in the usual manner.

One side ofv the'body 1 is formed With a recess-21, in which is mounted a condenser `22, connected in the primary circuitoi the li'nd-uctance coilin a manner Well known-rn the a-rt, iler-reducing the arcing acrossrthe breakerA point, a cap being.r removably positionedj" over-'the Vcondenser-l on closing the recess'ZL'in a manner clearly illustrated in Figures 1l and*i 3. A binding posti E24 is provided on the, side of the body" above the cap `23jpf'or one side of" the-.circuit tof the condenser, so- :that ,itA mayE beY properly grounded; in the usual"mannery While the other; side off"tl"1e condenser.- "isf connected to the wire extending to the binding. post i 19.,

I Frein1` the foregoing; "description, iti' will The plate 11 is thus be seen. that a novel construction has been provided for combininga distributor cap and an ignition coil, in a unitary structure, in, order` to increase the efficiency of operation thereof, and eliminate numerous disadvantagcsnow experienced in the inanner of mounting and connecting these elements,` which are constructed separate.

In some ignition systems, it is not necessary to combine the condenser' inthe body structure as illustrated, Vin View of' the, fact that a separate condenser construction is connected' with the breaker point` in which case the `body may be manufactured for taclnnent to a distributor, Without they rc- `cess 21 andA theremaining structure mount "cal` body having an axial bore and' a plurality ofi passages arranged inV circumferential relation around' said bore formed therein,y an induction coily mounted in the bore,'an-attaching capiitted to` onel end of the body to forma cover' and? formed for attachment'V tol adistnib'utor`V section, an end plate -niounted'r onf-the other end ofthe body and" havingy openings registering with the circumiierentially arranged passages, and a pluralityfot rods: head-ed at one .endly and 'entendedI through the cap, body and end plate' in spaced parallel circumferential relation, rhaving terminals secured theretor to hold' the cap, bodyand end platein rigid assembled relation, the headson theI rods forming contacts orf cooperation 'with the distributor, said 'terminalsbeing formed. to receive electrical connection to` interpose said rods: inthe-ignition circuit in a predeterminedmanner,` andysaidI body being' provided With tenminals having electrical conneet-,ion withpredetermined portions of said inductiony coil,I whereby tlajesame mayav be interposed? int the ignition circuit.
